OPHTHALMIC MOUNTING.

To all whom it may concern: Be it known that I, J OEL WELLs, a citizen of the United States, res dmg at Southbridge, in the county of Worcester and State .referen'ceTto improved means forretaining the same in position on the face of the wearer. V

The leading object of my invention is the provision of a novel and improved form of pad or retaining member which will so engage the nose as to resist to a maximum any tilting or rotating movement of the mounting on the face.

A further object of my invention is the provision of an improved guard particularly adapted to resist that form of tilting or-outward swinging of the glasses which occurs when the wearer is leaning over as to pick up something from the floor or in other unnatural positions.

Other objects and advantages of my im grammatic side elevation illustrating my mounting in position on theface of the wearer when leaning over. Fig. IV represents a view of a modified construction of my guard used in connection with a spring bridge mounting, Fig. V represents a view of'the same applied to an ordinary fingerpiece mounting. Fig. VI represents'an enlarged sectional view on the line VIVI of Fig. II, illustrating one form of my upper ad.

views, the numeral 1 denotes the lenses of I the mountingconnected by the bridge.mem-' ber 2 which may be either of-the rigidor spr ng type as may be preferred, my guard being adapted to operate with. either form of bridge.

. In. that form of myinventionillustrated' inFigs. I to III inclusive, I have illustrated a type of mounting in which the lower guard or bearing member 3 is rigidly secured 'to'the mounting, while an upper movable arm 4 is employed carrying my improved gripping member. My gripping member in the form here illustrated comprises the basal plate or bearing member 5 having projectinginwardly therefrom the contact members 6 which may be of any desired configuration,

either square, round or otherwise as is shown in thedifierent views, and which may be of any desired number, either two, as shown in Fig. II, three, as shown in Fig. IV, or four as shown in Fig. V, it not being my intention to limit myself to any particular number of these points.

In Fig. IV in place of the fixed lower and having the rearwardly extending arm 4:ca-Iirymg the upper anchormg member.

'80 movable upper bearing members I haveshown my guard as consistlng of a single plece held in an ordinary stud box 7, and I V Fig. V represents a view quite similar to to move in the direction of the arrow 9 off of the face of the'wearer, the chief loosening movement being noticeable at the pad 3. In

this movement the mounting would nor-.

face and thus allow of some loosening or downward swinging movement of the mount mg. It 1s to counteract this loosening movement and securely retain the glasses in position under all conditions that I have provided my improved guard.

It is to be noted that I have'shown one of the two members 6 as disposed near the upper and the other near the lower end of the upper bearing member or pad 5. The purpose of this should be readily apparent by reference to Fig. III, from which it will be seen that should the mounting have any tendency to rotate about the point 10 as a center the upper member 6 will engage the nose to resist any swinging movement thereof in the direction of the arrow 11 while the lower member 6 will engage the nose to resist any movement in the direction of the arrow 9, and consequently the mounting will be firmly yet comfortably held in place against any such twisting movement and liability of slipping off of the face is consequently reduced to a minimum. In addition, however, to resisting any loosening movement with the nose in the position shown in Fig. III, my projections 6 will satisfactorily engage the nose when the head is in upright position to resist any forward tilting or sliding movement of the upper portion of the 'mounting as a whole or any outward twisting thereof, as when the same tends to loosen in the ordinary manner.

From the foregoing description taken in connection with the accompanying drawings the construction of my device should be readily apparent, and it will be seen that the members 6 are extremely eflicient under all conditions and are particularly efficient under the peculiar conditions met with when a person is leaning over.

It will be noted moreover that I may make use of either the two points shown in Fig. III, the three points shown in Fig. IV, or the four points shown in Fig. V, in any desired relation to each other, or on any guard, and thus take care of any swinging on anarc at either two opposed points or at more than two points as may prove necessary according to the particular conditions of service, or the peculiar configuration of the nose to be fitted therewith.

I claim:

1. The combination with a main guard, of a pad therefor comprising a base plate, an attaching member intermediately secured thereto and projecting therefrom, and sepa rate bearing portions, carried by the pad near the ends thereof and extending inward to engage the nose and prevent rotative movement.

2. The combination with a lower bearing member, of an arm extending thereabovc, a supporting pad carried by the arm, and a contact point carried by the pad and projecting inward therefrom adjacent each corner thereof for engagement with the nose.

3. In an ophthalmic mounting, an upper holding pad for securing the same in position on the face, said pad being of minimum necessary length to prevent tipping outward of the mounting at the top or outward rotation from the bottom, means carried by the mounting and engaging the pad intermedi ate the ends thereof for connecting the pad and the mounting, the said pad being relieved at the center whereby the end portions only of the pad Contact with the face of the wearer for retaining the mounting, the front edges of the contacting portions being substantially straight to resist to a maximum any rotating movement of the pad about its center.

In testimony whereof I afiix my signature in presence of two witnesses.
